Deciphering Pulsatile Behavior and Flow Characteristics in Stenosed Arteries: A Comprehensive Investigation
Vivek Kumar
Abstract: This study explores how Bingham plastic fluid behaves in narrowed arteries, using a two-layer model to analyze how the fluid pulsates within the artery. By employing perturbation techniques, the research investigates key factors like velocity, shear stress, and flow rate. The graphical representation of the results indicates that as the artery's radius increases, the velocity of fluid flow decreases, suggesting that narrower arteries have faster blood flow than wider ones. Furthermore, the graphs demonstrate that over time, there's a rise in resistance to flow within the narrowed arteries, implying that as arterial stenosis progresses, so does the resistance to blood flow. Understanding these dynamics is crucial for comprehending how blood moves through narrowed arteries, particularly in conditions like atherosclerosis, where plaque buildup leads to arterial blockages. By shedding light on how blood flow is affected by arterial narrowing, this study provides insights that could inform the diagnosis and treatment of cardiovascular diseases. Therapeutic approaches aimed at managing arterial stenosis may benefit from considering the fluid dynamics within narrowed arteries.
